    I breathe so much better with Blue Pure 511

    My BlueAir purifier suddenly stopped working after a year and when I contacted customer service, they replaced it immediately. My new Blue Pure unit arrived within a week and I am breathing easily again. I have allergies and this air purifier really minimizes the symptoms I have. Thank you BlueAir!!

    Clean Air Blessing

    Firstly, I never leave product reviews because my time is always full with life. But, I needed to do so on this product. It has been such a wonderful addition to my home that I actually purchased a second one for another room in the house. When it came time to change the filters, I was astonished, to say the least, of its effectiveness in cleaning the air in my home. It literally blew my mind. I must share some pictures of all the dust and pet dander ( I have a dog ) it collected. I routinely change my HVAC air filter every other month as well as having my air ducts cleaned and I was still collecting dust and other air particles with my purifier.

    Look at my before and after of the filters when I changed them and then look at the collection of particles on the cover. I do clean my home. I even dust my walls. I do a lot and I still collected so much on my purifier. That's how powerful this purifier is and I totally recommend buying one. Especially this brand. It catches particles we don't see. Can you imagine breathing all of that in? No thank you.

    Thank you BluAir

    The BEST air purifier in THE WORLD!

    I've always had an air purifier in every room for most of my life. We recently had air quality issues due to dust and dander (despite rigorous cleaning), and none of our purifiers were doing the trick. Because of the way the air flows in our house, everything gets trapped, and ends in my son's corner room, which caused allergies. We have been using this small, Blue Pure 511 in his room for almost two weeks now, and it's AMAZING. Crystal clear air, so pure, so amazing, NO ALLERGIES. We will now be switching all our purifiers to Blue Air! 10/10! What a lifesaver! Thank you!
